Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working.
Allow the engine to cool down before starting repairs.

2. Inspect and Replace Air Filter

Remove the air filter housing cover.
Take out the old air filter and inspect it for dirt or damage.
Replace with a new air filter if it is dirty or damaged.
Reassemble the air filter housing securely.

3. Clean Throttle Body

Remove the throttle body from the intake manifold (note torque specifications for reinstallation).
Use throttle body cleaner and a soft rag to clean the interior surfaces thoroughly.
Reinstall the throttle body, ensuring all gaskets are in place and secure.

4. Check and Replace Spark Plugs

Remove the ignition coil covers (if applicable).
Extract the spark plugs using a spark plug socket.
Inspect the spark plugs for wear; replace with new plugs if necessary (specify gap as per manufacturer’s recommendation).
Reinstall the ignition coils and covers.

5. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Start the engine and monitor the fuel pressure; compare it against manufacturer specifications.
If pressure is low, check the fuel pump, filter, and injectors for faults and replace as needed.
